Why does your Chrysanthemum Arobas have yellow leaves? Diagnose the cause and fix it with our step-by-step guide.
As a heavy feeder during its growth phase, 'Arobas' requires significant nitrogen to maintain its lush foliage. A lack of nitrogen causes older, lower leaves to turn pale yellow before progressing up the plant.
Chrysanthemums are sensitive to 'wet feet'; excessive moisture in the substrate displaces oxygen, leading to root hypoxia. This prevents the plant from transporting nutrients, resulting in general chlorosis (yellowing).
Fungal pathogens like Pythium thrive in overly damp Chrysanthemum pots, attacking the root system. This leads to rapid yellowing of foliage and a loss of turgidity in the stems.
Two-spotted spider mites feed on the underside of 'Arobas' leaves by piercing cell walls. This causes a characteristic fine, yellowish stippling pattern across the leaf surface.
